Introduction
The Eaton Inverter is designed to create 1.8kW of pure sine wave 115VAC 60Hz power from a 12V battery source. The units
low THD (<2.5% typical) can power sophisticated electronics that may not work with modified sine wave inverters. Unit also
has high surge capability to power up hard to start loads like power tools, refrigerators or pumps.
The Eaton Inverter is protected against most abnormal conditions found in the automotive environment.
The unit has an under voltage alarm and shut down that prevents the batteries from becoming depleted.
A warning alarm will sound when the maximum power output is being reached. An alarm will also sound if unit is
overheating. If any of these conditions are not corrected, the unit will turn off safely to protect itself.
Some models include a three stage temperature compensated battery charger that maximizes the life of the batteries. It can
be configured for AGM, flooded or Gel lead acid batteries.
Eaton inverters include a Shore Power bypass feature. When AC power (Shore Power) is detected at the AC input, the unit
powers all accessories from this available power source. If the inverter automatically detects that AC input is removed, it
becomes an independent AC supply.
Inverter input current could be as high as 200A in the 1.8KW unit. Special care has to go into evaluating the proper sizing of
batteries, wire gauge and length.
The inverter’s logic is powered by the 12V input battery. The unit current draw when power is off is typically less than 2mA.
When the inverter is turned on with no load connected to its output it will typically draw less than 0.5A.
Operation efficiency is input voltage, load and ambient temperature dependent, but it is typically 90%.
The Eaton inverter will not withstand reverse polarity. Permanent damage will occur and is not covered by warranty.
